HENRY W. JACOBS, OF TOPEKA, KANSAS.

TRACK-CARZAND TOOL-DRIVING MACHINE.

To all whom it may concern:

Be it known that I, HENRY W. JACOBS, of Topeka, in the county of Shawneeand in the State of Kansas, have invented a certain new and usefulImprovement in Track-Cars and Tool-Driving Machines, and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in whichFigure 1 is a side elevation of a machine embodying my invention," Fig.2 is a top plan view of the machine of Fig. 1; Figs. 3 and 4 are similarviews of another embodiment of my invention; Fig. 5 is an end view ofthe machine of Figs. 3 and 4, and Fig. 6 is a side elevation of a carembodying my invention, showing the car in actual use.

The object of my invention has been to provide a car by which rails canbe set a standard distance apart, and holes may be drilled in railwayties and spikes may be secured in such holes, and which shall enableboth of these operations to be carried on at the same time and to suchends my invention consists in the track car and tool driving machinehereinafter specified.

In carrying my invention into practice I provide a car body 10, whichmay be of the usual construction for cars used by trackmen. This body issupported upon axles 11 and 12, having wheels secured thereto. Upon thecar is mounted a motor 13, which is preferably an explosive motor. Theshaft 14 of this motor has fixed to it a member of a clutch 15, theopposite member of the clutch bein fixed to a sprocket gear 16, which islooseiy mounted u on the shaft. The axle 12 is also provide with asprocket gear 17 and a sprocket chain 18 asses around the said sprocketgears. In t 's manner the car can be ropelled by the motor, uponthrowing in t e clutch 15.

The opposite end of the shaft 14, from that having the clutch 15, has abevel pinion 19, which, throu h a bevel gear 20, drives a shaft 21,preferabIy extendin longitudinally of the car body. Preferab y near oneend of the car body is a shaft 22 parallel to the shaft 21, and having slined upon it an intermediate clutch memfi ner 23. Said clutch membercan be shifted by a lever 24 and handle 25 to engage either a clutchmember 26 or a clutch member 27 on opposite sides of the intermediateclutch member. The clutch Specification of Letters Patent.

Application filed January 25, 1908.

Patented June 23, 1908.

Serial No. 412,687.

member 26 is secured. to a gear 26- meshing with a pinion 28 on theshaft 21. The clutch member 27 is secured to a gear 29 meshing with apinion 30 on the shaft 21. Thus by throwing the intermediate clutchmember 23 either into engagement with the member 22 or with the member27, the shaft 22 can be driven at a relatively high speed, or at arelatively low speed, respectively. A flexible shaft 31 is connectedwith the shaft 22, and transmits power through beveled gears to a drill32 within a casing 33. The casing has the usual handles for a workmanin. using the drill.

Preferably at the opposite end of the car is a shaft 34 parallel to theshaft 21, the shaft 34 having splined upon it an intermediate clutchmember 35. This clutch member is shiftable by a lever 36 and handle 37to engage either a clutch member 38 or one 39 on opposite sides of theintermediate clutch member. The clutch member 36 is secured to a gear 40meshin with a gear 41 on the shaft 21, to provide s ow rotation of theshaft 34. The clutch member 39 is secured to a gear 42, meshing with ainion 43 on the shaft 21 to secure a rapi rotation of the shaft 34. Aflexible shaft 44 is secured to the shaft 34 and transmits motionthrough beveled gears to a spike driver journaled in a casing 45, whichcasing has handles 46 for directing the spike driver.

In the operation of the above illustrated car, the trackmen may propelthemselves to the point where they are to work by throwing theintermediate clutches 23 and 35 to midway position, in which they do notengage any clutch member, and by engagin the clutch 15 so that thesprocket gearing rives the car wheels. Upon arriving at the point wherework is to be done, the clutch 15 is disenga ed, and one man using thedrill goes ahead of the car drilling the holes which will later beoccupied by the screw spikes. Another man follows the car using thespike driver, and drives the screw spikes into the holes which are madeby the drill, and as this can be done while new holes are being drilled,both operations of drilling the holes and driving the spikes can proceedat the same time. If it is desired to remove a spike, this can be doneby reversing gears in the casing 45.

It will be evident that my car, by provid ing the drill at the forwardend of the car and the spike driver at the rear end of the car, effectsa great saving in time, because the two operations of making the holesfor the spikes and driving the spikes can be performed at the same time.It will also be evident that my car, while having the advantage uststated, will be useful. in carrying men to and. from their work; fordrilling holes for other purposes as in bridge repair work; for runningthe air blast of the forges on a bridge, and to furnish power for otherpurposes. It will also be evident that the car will be useful indrilling holes in Ii sh plates and rails.

Another embodiment of my invention is illustrated in Figs. 3 and 4. Thecar body is provided with forward and rear axles 47 and 48,respectively, upon which are the usual car wheels. The car body consistspreferably of side bars 49 formed into handles at each end, the sidebars being connected by end beams 50, and bolts 51 being used to drawthe side beams against the end beams. A floor is formed of boards 52extending from one end beam to the other. At each end'of the car acasting 58 is secured upon the end beams, and parallel pipes 54 arethreaded into such castings. A motor 55, preferably a two cylinderexplosive motor, is secured to the said pipes. The shaft 56 of the motorextends parallel to the rails to a forward friction clutch 57 and a rearfriction clutch 58, which clutches are operated, respectively, by handlevers 57 a and 58 The driven member 59 of the friction clutch 57 iscarried by a shaft 60 mounted in a bearing 61 secured to the carplatform. A flexible shaft 62 is connected to the shaft 60, and carriesat its opposite end a device for forming holes for railway s ikes,preferably a boring device 63. This eviee preferably has an up )erhandle 64, by which it may be managed with one hand, and horizontalhandles 65 and 66, by which both hands may be used to bring pressure tobear upon it.

The motor shaft also carries a bevel gear 67 which meshes with a bevelgear 68 on the shaft of a change speed gear 69 of an known t pe, such,for instance, as the we l-known c ange speed ear used on automobiles, bywhich the sha t of such change speed gear a can be driven forward ateither a slow or a rapid speed, and backward, or stopped. The changespeed gearing drives a sprocket gear 73, connected by a sprocket chainwith a sprocket gear 7 4 on one of the axles. In this manner the car canbe driven forward at various speeds, or backward, or can be stopped.

The friction'clutch 58 referably has its member 75, that is carried bythe lever 58, fast on the shaft of the motor. The loose friction clutchmember 76 has a inion 77 which meshes with a gear 78 on a s aft havingbearings 79 and 80 secured on the car platform, the rear end of saidshaft being connected with a flexible shaft 8], which. operates a spikedriver 82, the latter being preferably of such form as to drive a screwspike.

The shaft 56 has the usual clutch 56 and crank 56 for starting themotor.

A casing is preferably formed over the motor, consisting of risers oruprights 83 that support forward and rear scats 841, the "I seats havingbetween them a back 85. The carbureter and gasolin tank can be placedbeneath these seats.

Forward and rear brake shoes 86 are hung from pins on the side bars ofthe frame, and are connected by toggle links 87, the middle pin 88 ofsuch links being connected by a ink 89 with the lower arm of a bellcrank 90, whose upper arm is connected by a rod 91 with a treadle 92, bywhich the brake may be operated.

At the forward end of the car I rovidc a device for readily spacing therai s at the standard distance apart so that they may be in position tobe speedily fastened by the use of the spike drilling and drivingdevices at the forward and rear ends, respectively, of my car. Suchspacing device preferably consists of bars 93 fastened at their upperends to the side bars of the car, the said bars 93 carrying a gage bar94 at their lower ends, said latter bar preferably having verticalrollers 95 journaled in its ends at such a height as to bear against theheads of the rails on their inner sides when the car is resting on therails. By means of this ga e the rails can be moved up against the relers and the car can travel along the rails so that the gagin andfastening of the rails can proceed wit rapidity.

I also preferably provide an emery wheel 96 which can be secured on thehigh speed flexible shaft to grind ofi the ends of rails for weldedjoints, or to grind the sides between the rail and guard rail in curves.For the purpose of grinding the tools, I provide a stand 97 on the carplatform, such stand having two clamps 98 to clamp the handles of theemery wheel, and having a rest 99, on which to rest the tool whenpresenting it to the emery wheel.

It is obvious that various changes can be made in the above illustratedconstructions which will be within the scope of my inven tion, and Idesire not to be limited beyond the terms of my claims and therequirements of the prior art.

I claim:

1. In a machine for working upon railroad tracks, the combination of acar, a motor, a device at the forward end of the car for making holesfor railroad s ikes and a device at the rear of the car for riving suchspikes.

2. In a machine for operating upon railroad tracks, the combination of acar, a
